Ajax request failing Rails

Question

I am a little stumped as to why my Ajax call is failing, It was working and cannot think of any changes that would have affected it. When i make the call i get an error in firebugs console that points to this in my jquery.js file

// Do send the request
// This may raise an exception which is actually
// handled in jQuery.ajax (so no try/catch here)
xhr.send( ( s.hasContent && s.data ) || null );

Firstly what does this mean?

My setup is like so

index.js.erb

<% if params[:type] == 'Tynewydd' %>
 $('#newsResults').html('<%= escape_javascript(render partial: 'tynewyddposts') %>');
<% end %>

index.html.erb

 <div id="newsResults">
   <div class="hero-unit">
     <h2> Welcome to your admin area</h2>
       <p> xxxxxxxx.</p>
         <p>xxxxxxxxx</p>
   </div>
  </div>

Link for ajax request

<li><%= link_to 'Tynewydd', posts_path(:type => 'Tynewydd'), :remote => true %></li>

Can anyone see what is going wrong here please or offer some debugging suggestions?

Any help appreciated

Edit

Controller

def index
@posts = Post.all
@tynewyddpost = Post.tynewydd_posts
@woodsidepost = Post.woodside_posts
@elmspost = Post.elms_posts
@sandpiperpost = Post.sandpiper_posts
@outreachpost = Post.outreach_posts
@companypost = Post.company_posts
@staffpost = Post.staff_posts

respond_to do |format| 
 format.html 
 format.js 

end

Ok so i am no longer getting the error, i had an undefined method error for nil class in the called partial, so now in the console I can see the response but the partial that is supposed to render does not display on my page

Thanks

can you remove <% if params[:type] == 'Tynewydd' %> from the .js.erb file and say if it's working? — Zippie

ok, for now don't put it back. Can you also put the _tynewyddposts.html.erb file? — Zippie

im doing a <% @tynewyddpost.each do |t| %> or do you want the whole file? — Richlewis

ok so just in-case anyone else runs into a similar issue changing $ to jQuery has solved the problem, so this

<% if params[:type] == 'Tynewydd' %>
 $('#newsResults').html('<%= escape_javascript(render partial: 'tynewyddposts') %>');
<% end %>

was changed to this

<% if params[:type] == 'Tynewydd' %>
  jQuery('#newsResults').html('<%= escape_javascript(render partial: 'tynewyddposts') %>');
<% end %>
